INTRODUCTION
In the mid-1990s,Internet created a platform for educators to offer learning online.Some training institutions simply converted existing training materials to online,text-based or PowerPoint electronic formats.These approaches failed to deliver the desired result as the context of learning was missing.In 1999,there was a breakthrough in e-learning with advances in authoring software.There was a dramatic shift from the formerly text-based and PowerPoint training materials into technology project,rather than an educational initiative.With an increase in the Internet bandwidth,developers have more media options to work on.Unfortunately,the greater freedom to use graphics and video resulted in a rash of arcade-style courses,most of which did little to enhance learning.
Hence,only the appropriate use of animation together with structured learning activities will optimise and enhance learning.A well-designed animation helps students to visualize and understand difficult concepts.Many students say "I need to visualize it in order to understand it." Schematics of hydraulic,electronics and pneumatic systems are excellent examples of using animation to add instructional value.However,attention must be paid to good animation design and the types of processes that will benefits from it in order to achieve the desired results.
DEVELOPMENT
Definition of Animation
Animation is the rapid sequential presentation of slightly differing graphics to create the illusion of motion.Animation can have greater purpose in illustrating a process than static visual,but it requires more information to be processed by the computer and thus requires higher bandwidth.Animations can be made with special techniques like Macromedia Flash,Director or GIF animator.More sophisticated 3D animations can be produced with 3D studio Max.
Animation can be presented in two ways:(1) preprogrammed dynamics,in which the learner is a passive viewer and animation is designed prior to showing (this includes all popular film animation such as Walt Disney cartoons) and (2) "interactive dynamics" (Brown’s term 1983),in which the animation is created on the fly,manipulated by the viewer,as in computer simulations.Adults learn from either types about equally,whereas children benefit more from the interactive animations,perhaps because of the intrinsic motivation of the latter,Rieber speculates.

导言
在20世纪90年代中期,互联网创造了一个平台,为教育工作者提供在线学习.一些培训机构根本转换现有的培训材料,以线上,基于文本或PowerPoint电子格式.这些方法未能交付预期的结果作为的背景下学习失踪.在1999年,有一个突破,在电子学习与进步,创作软件.有一个戏剧性的转变,从以前的基于文本和PowerPoint的培训材料,到科技项目,而不是一个教育的倡议.与增加在互联网的带宽,开发商有更多的媒体选择的工作.不幸的是,更大的自由使用的图形和视频功能,导致轻率的商场式的课程,其中大部分几乎没有,以加强学习.
因此,只有适当使用动画一起有条理学习活动,将优化和加强学习.一个设计良好的动画帮助学生可视化和理解困难的概念.许多学生说：“我需要它的可视化,以了解它” .示意图液压,气动和电子系统是很好的例子使用动画添加的教学价值.然而,必须注意良好的动画设计和类型的进程,将受益于它,以达到预期的效果.
发展
定义动画
动画是快速序贯介绍略有不同的图形创造的幻想议案.动画可以有更大的目的在说明一个过程较静态的视觉,但它需要更多的信息处理由计算机,因此需要更高的频宽.动画可以作出具有特殊技术一样的Macromedia Flash ,主任或GIF动画.更先进的3D动画可以制作用3 D Studio最高.
动画可以介绍的方法有两种：（ 1 ） preprogrammed动力学,在其中学习是被动的观众和动画设计之前,显示（这包含了所有流行的电影动画,如华特迪士尼卡通）及（ 2 ） “互动式动态” （布朗的任期1983年） ,其中动画是建立在飞,操纵观众,因为在计算机模拟.成年人的学习,无论从类型有关,同样,而儿童更有利的互动动画,也许是因为内在的动机,后者rieber推测.
